Patent GB-2381322-B (GB)
Title: Loop impedance meter
Inventor: BATTEN DOUGLAS WILLIAM
IPC: G01R27/18
Filed: 2001-10-24
Granted: 2005-09-14
Abstract: A loop impedance meter for testing an A.C. electrical mains supply, including an electronic control circuit for connecting a load resistance intermittently between the A.C. mains supply terminal and the earth terminal to measure the potential difference between those terminals and to provide an indication of the loop impedance of the A.C. mains supply from that potential difference, wherein the control circuit is arranged to allow a train of short pulses of current to flow through the load resistance and the loop, the pulse train beginning its sequence with a first train of pulses for preconditioning any residual circuit device (RCD) present in the loop to temporarily desensitize it, wherein the first train of pulses is followed by one or more measurement pulses, the pulses of the first train being of generally increasing width.

Title: Improvements relating to thermally-responsive switches
Inventor: O'NEILL ROBERT ANDREW
IPC: H01H37/54
Filed: 2001-11-14
Granted: 2005-07-13
Abstract: A contact thermostatic switch has a dished, snap-acting bimetallic disc 5 cantilevered from one end of a diameter. The edge of the disc is loosely retained between a housing moulding 1 and a metal cap 6 secured to the moulding. At the other end of this diameter, the edge of the bimetallic disc engages a pip 4d on one end of a lever 4 which is pivotally-mounted in the housing at its other end. When the bimetallic disc 5 snaps to its oppositely dished configuration, it moves the pivotally-mounted lever 4 so as to determine the condition of a set of switch contacts by virtue of the end of the lever 4 which carries the pip 4d also having depending fingers 4c which abut a moving-contact carrying leaf spring 2b of the switch. The cantilevered mounting of the bimetallic disc and its interaction with the lever enables a smaller than conventional disc to be used, with consequent significant cost savings, without prejudicing the operation of the switch.

Title: Control of memory devices possessing variable resistance characteristics
Inventor: FANG TZU-NING
IPC: G11C16/02
Filed: 2005-09-19
Granted: 2008-04-09
Abstract: Systems and methods employing at least one constant current source to facilitate programming of an organic memory cell and/or employing at least one constant voltage source to facilitate erasing of a memory device. The present invention is utilized in single memory cell devices and memory cell arrays. Employing a constant current source prevents current spikes during programming and allows accurate control of a memory cell's state during write cycles, independent of the cell's resistance. Employing a constant voltage source provides a stable load for memory cells during erase cycles and allows for accurate voltage control across the memory cell despite large dynamic changes in cell resistance during the process.

Title: Clocked comparator
IPC: H03K5/08
Filed: 1979-01-24
Granted: 1982-04-07
Abstract: A sensitive high speed clocked comparator for use with low level differential logic circuits which utilizes an amplifier, a Gilbert Gain Cell, and load devices to amplify the difference between analog voltages being compared, and a high speed latch to increase the output voltage level of the Gain Cell up to the level of logic signals used in low level differential logic circuits. The circuit has two modes, a "follow" mode wherein the amplifier and Gilbert Gain Cell cause an unbalance in the currents through two load devices responsive to any difference in input voltage, and a "latch" mode wherein a latch causes the current unbalance to increase and to latch. The modes are sequentially selected by clocking.

Patent GB-2105823-B (GB)
Title: Butterfly valve
Inventor: BEAUCHAMP DAVID COLSTON
IPC: F16K1/226
Filed: 1982-09-08
Granted: 1985-03-27
Abstract: A fire-safe butterfly valve (FIG. 2) provides bi-directional sealing. In normal duties a polymeric seal provides forward and reverse sealing against the edge of the valve disc, the polymeric seal being resiliently loaded in the axial direction of the valve by a resilient metal ring. The metal ring provides a bi-directional seal with the disc edge in the event of destruction of the polymeric seal by fire. The metal ring in transverse cross-section consists of an arm having a curved radially inner end presenting a convex surface for engagement with the disc edge. For fluid pressure acting from the smaller diameter side of the disc, in the burnt out condition, the curvature of the radially inner end of the metal ring gives rise to an increased sealing force with the disc edge as the disc moves in response to the fluid pressure and the ring inner end remains in rolling contact with the disc edge.

Title: Multiplexed digital data transmission
Inventor: CHAMBERS JOHN PHILIP
IPC: H04N7/04
Filed: 1984-04-13
Granted: 1986-10-29
Abstract: A digital transmission system for transmitting, e.g., television sound has two packet type indicators indicating, e.g., mono/stereo transmission. Normally the same packet type indicator is transmitted for a long sequence of packets. To provide synchronising information to enable, e.g., appropriate timing of the sound signal to the associated video signal, the packet type indicator for a single packet is changed to an indicator which is inappropriate to the packet concerned but is appropriate to another type of packet.

Title: Appts. for high pressure peptide synthesis
Inventor: VERLANDER MICHAEL STEPHEN
IPC: C07K/
Filed: 1982-04-02
Granted: 1987-02-18
Abstract: A process for synthesising a polypeptide chain on an insoluble solid support, utilises a series of stepwise coupling reactions performed under high pressure. The appts. used includes reservoirs for a deprotecting agent, a solvent, a neutralising agent and aminoacids. Each reservoir is selectively coupled to a continuous flow reactor packed with the insoluble support. The fluids from the reservoirs are transferred under high pressure through the reactor. A recycle loop is used to recycle the amino acid back through the reactor. The loop includes a reagent reservoir where the recycling fluid is accumulated. The accumulated fluid is transfered back to the reactor by a recycle pump. The reactor is maintained under high pressure so that the synthesis occurs under a pressure of at least 40 psi. The appts. is used for the synthesis of peptides, polypeptides and proteins. The reaction rate is rapid compared with conventional solid phase reactions. Long chain polypeptides of greater than 20 amino acids can be prepd. on a large scale with little side reactions. The final prod. requires little purificn. after cleavage from the support.
